This invention relates to certain new and useful improvements in dentalapparatus, and more particularly toapparatus for use in cleaning teethand massaging gums.

An object of my invention is the provision of dental apparatus which iseconomical, and yet which will perform more than one function in oneoperation by the operator. The apparatus is adapted to be used with theconventional dental engine, and may be used for cleaning the teeth, andat the same time will be very useful as a massage instrument in treatingthe under-gum margins.

The union of a dental cleaning cup and the brush in my apparatus causeseach of the articles united to perform its function more efficiently.Some of the many advantages obtained are hereinafter set out. Because ofthe construction of the cup it will aid materially in retaining thebristles of the brush in a close compass and consequently will aidmaterially in giving the bristles additional strength. Then the deviceisto be used with any cleaning powder or abrasive material, the cup,surrounding the bristles will aid in retaining the material used inclose proximity to the bristles, and at the same time will prevent thebristles themselves from entering beneath the gum margins.

It is known that sometimes the bristle socket of the brush causes injuryto the gums and teeth by striking against them, but in my apparatus thisdifficulty is obviated because of the bufling action of the cup. At thesame time the bristles of the brush aid in forming a support for thedental cup, and consequently give it the massaging operation. I haveProvided means for limiting backward longitudinal movement of the cup,and althoughthe cup is retained upon the brush head, still it mayberemoved by the operator at will.

Other objects will appear hereinafter.

I have illustrated my invention in the accompanying drawing, in which:

tion 22 and a crimped bristle engaging portion23. Y v v 1 It can v beseen that the cup 24 used with height than cup 15 used with the otherform. Because of the frictional engagement of cup 15 on crimped portion23, and also because of offset shoulder 22, the backward longitudinalmovement of cup 24:; on crimped portion 23 is limited or entirelyobviated. In .99

other respects cup 24 is similar to cup 15 in that it is provided with aflared end 25 having an internally serrated periphery 26. The modifiedform illustrated in Figs 7 and 8 may be used interchangeably with theform of brush and cup illustrated in the remaining figures, and willperform its functions when so used.

It can now be seen that the advantages 10 pointed out above are only afew of those V to be realized from the use of my apparatus. In additionto those, it will be noted that because of the simple construction thecup may be removed from eitherform and thus sterilization of theinstrument may be greatly facilitated. However, because of the cheapnessof construction, the cup and brush, may bediscarded after use, ifsodesired; It can be seen also that because of the construction the cupwill perform its functions in a better manner than if it were usedalone, and the brush will likewise be used to a greater advantage thanwhen it is used by itself.- In addition tothese advantages, the teethmay be cleaned; polished and brushed, and at the sametim'etheunder-inargins of the gums may be massaged so as to keep them ina healthy condition and free from pyorrhea.

It can readily be seen that various struc- 3 tural alterations may bemade without departing from the spirit and scope of my invention, andhence I'do not wish to be limited to the precise structural-detailsillustrated, but wish to avail myself of all changes coming within'thescope of the appended claims.
